If you wish to create custom applications that work with MOM you must reference the MOM Management Server Class Library (MCL). The library is installed on all MOM Management Server computers. Applications that use the library must be developed, tested, and deployed on MOM Management Server computers. To create a new MOM application first you must add a reference to Microsoft.Mom.Sdk as well as Mom.Context; these assemblies are stored in the SDK Bin folder of the MOM program files folder, which is in the computer's Global Assembly Cache GAC. See the following code for an example.
